  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an example of the configuration of a power management system 100 according to an embodiment of the present invention. As shown in FIG. 1, the power management system 100 is connected to a power management server 10, a store terminal 21, electrical devices 21 a to 21 g connected to the store terminal 21, a delivery center terminal 22, and a delivery center terminal 22. Electrical equipment (not shown). In FIG. 1, only the store terminal 21 installed in the store A, the electric devices 21a to 21g connected to the store terminal 21, and the delivery center terminal 22 installed in the delivery center A are disclosed. It is good also as a structure containing the electric equipment connected to the terminal (a shop terminal and a delivery center terminal) each installed in 1 or 2 or more stores of this, or a delivery center, and the terminal. Moreover, although the electric equipments 21a-21g are illustrated in FIG. 1, what kind of thing may be sufficient if it is an apparatus which receives electric power supply and operate | moves. Hereinafter, the store terminal 21 will be described as an example.

  The power management server 10 and the store terminal 21 are each connected to a communication network 30 such as a LAN or the Internet. In addition, the electrical devices 21a to 21g are connected to the store terminal 21 via a communication network 40 such as a LAN or a wireless LAN.

  The power management server 10 is managed by a system administrator of the system 100 and is configured by an information processing apparatus such as a WWW server. Further, the store terminal 21 is managed by the store A and is configured by an information processing device such as a personal computer.

  The power management server 10 executes various processes for stopping power supply to the electrical equipment installed in each store when a predetermined condition is satisfied. In addition, the power management server 10 includes a power management master DB 11 that stores a power management master described later, and a power company provision information DB 12 that stores power company provision information described later. The power management master DB 11 and the power company provision information DB 12 may be inside or outside the power management server 10.

  FIG. 2 is an explanatory diagram illustrating an example of a power management master. As shown in FIG. 2, in the power management master, electric device information in which an ID (electric device ID) of a controllable electric device installed in each store is associated with a name of the electric device is registered. Has been. In addition, as shown in FIG. 2, the power management master is set with electrical equipment information of electrical equipment installed in each store for each store, and each power saving level or emergency level (this In the example, the electric device information of the electric device whose power supply is to be stopped is set in three levels (levels 1 to 3).

  An electric device that does not interfere with store sales even if power supply is stopped is associated with a lower power saving level and an emergency level. In this example, three levels of power saving level and emergency level are set, and an electric device that does not interfere with store sales even if power supply is stopped is associated with level 1 of the lowest level. In addition, an electrical device that has a problem that the store operation is hindered when the power supply is stopped but that can continue the operation is associated with the intermediate level 2. And the electric equipment which shows the trouble of the grade which cannot continue a shop business when electric power supply is stopped is matched with level 3 of the highest level. The level associated with each electrical device is determined in advance by a system administrator or the like, and a power management master is set according to this determination.

  In this example, the power saving level and the emergency level are set in three stages, but may be two stages or four or more stages. Moreover, in FIG. 2, the level with which each electric equipment is matched is an example, and may be matched with another level. Further, the power saving level and the emergency level may be divided into different numbers of stages.

  Here, the “power saving level” is the power supplied to the entire target area (for example, the area under the jurisdiction of the power company that supplies power to the area where the store is located: specifically, Hokkaido, for example). The supply power indicated as the power production status on the supply side, etc. The ratio of the expected power usage to the power supply a little ahead of the current time, for example, including the power supply for 12 hours ahead. Is a level that indicates the recommended level of power saving when there is a need to reduce power consumption. Therefore, for example, when the power saving execution power usage rate of the entire target area is extremely high (for example, 88%), it is necessary to quickly and significantly reduce the power usage amount, so the power saving level becomes the highest level. For example, when the ratio of the power usage to the power supply of the entire target area is higher than a predetermined threshold (for example, 80%), it is necessary to reduce the power usage amount, so that the power saving level is the lowest level. Become. In this example, for example, when the ratio of the used power to the supplied power of the entire target area becomes 80%, it is judged as level 1, when it becomes 85%, it is judged as level 2, and when it becomes 88%, it is judged as level 3. And This determination may be made by an administrator who manages the power management server 10, or a notification from the server device managed by the power company (notification of the ratio of the power saving implementation power usage rate of the entire target area). The received power management server 10 may determine automatically. Further, the power saving implementation power usage rate is compared with an expected power usage rate included in power company information described later.

  In addition, the “emergency level” is the ratio of the power used to the total power supplied in the target area (for example, an area under the jurisdiction of a power company that supplies power to the area where the store is located: specifically, Hokkaido, for example). It means a level indicating the urgency of the response when it is necessary to reduce the amount of power used, for example due to the increase. Therefore, for example, when the ratio of the used power to the supplied power of the entire target area is extremely high (for example, 98%), it is necessary to quickly and drastically reduce the power usage, so the emergency level is the highest level. Become. For example, when the ratio of the used power to the supplied power of the entire target area is higher than a predetermined threshold (for example, 90%), it is necessary to reduce the power usage amount just in case, so the emergency level is the lowest level. Become. In this example, for example, when the ratio of the used power to the supplied power of the entire target area becomes 90%, it is judged as level 1, when it becomes 95%, it is judged as level 2, and when it becomes 98%, it is judged as level 3. And This determination may be made by an administrator who manages the power management server 10, or a notification from the server device managed by the power company (notification of the ratio of the used power to the supplied power in the entire target area). The received power management server 10 may determine automatically.

  FIG. 3 is an explanatory diagram illustrating an example of information provided by the electric power company. The power company provision information is information used by the power management server 10 to derive the expected power usage rate, and is acquired by the power management server 10 from a server device managed by the power company, for example. In this example, the information provided by the electric power company corresponds to the same day, the same week, and the same day of the previous year (for the same day, the previous day, the previous day, and the previous day). Power consumption on the day to be.), Including supply power and expected power usage.

  Here, in this example, the power management server 10 calculates the ratio of the average value of “the previous day's results” and “the previous day's equivalents” to “the supplied power” for each time zone, Rate "is registered in the information provided by the power company. Note that the method for calculating the expected power usage rate is not limited to this, and any method can be used as long as it is considered to be appropriate as a calculation method for predicting the ratio of the power usage amount to the supplied power before the current time. Further, when the server device managed by the power company provides the power management server 10 with information including the expected power usage rate, the power management server 10 extracts the expected power usage rate from the provided information. Also good.

  Next, the operation of the power management system 100 of this example will be described.

  FIG. 4 is a flowchart illustrating an example of power management processing in the power management system 100 of the present example. Here, in accordance with the operation of the administrator X managing the power management server 10, the power management server 10 instructs the electrical terminal to forcibly stop the power supply to the store terminal 21 ( That is, here, it is assumed that only information related to the store A is registered in the power management master, and the case where the power supply to the electrical device is urgently stopped by an instruction from the store terminal 21 will be described as an example. It should be noted that explanations may be omitted except for processing particularly related to the present invention.

  In this example, it is assumed that the power management process is always executed while the power management server 10 is in operation.

  In the power management process, first, the power management server 10 determines whether or not the power company provision information has been acquired (step S101). If it is determined that the information provided by the power company has not been acquired (N in step S101), the power management server 10 proceeds to the process in step S104 described later.

  On the other hand, for example, if it is determined that the power company provision information has been acquired from a predetermined server device managed by the power company (Y in step S101), the power management server 10 calculates an expected power usage rate using a predetermined calculation formula. (Step S102) (see FIG. 2).

  When the predicted power usage rate is calculated, the power management server 10 refers to the power management master and the information provided by the power company, and the calculated predicted power usage rate is a time period in which the calculated power usage rate exceeds the power saving implementation power usage rate indicated by the power saving level ( Hereinafter, “power saving time zone” is specified (step S103).

  When the power saving time zone is specified, the power management server 10 specifies the current time by a known method, and whether or not the current time is a predetermined time before reaching the specified power saving time zone (for example, 5 minutes before). Is determined (step S104). Here, if it determines with not having reached the specified power saving time slot | zone (N of step S104), the power management server 10 will transfer to the process of step S101.

  On the other hand, if it is determined that the specified power saving time zone has been reached (Y in step S104), the power management server 10 refers to the power management master and determines the power saving execution power usage rate that would exceed the calculated expected power usage rate. An electric device corresponding to a power saving level equal to or lower than the power saving level shown is specified as an electric device to be stopped for power supply (hereinafter referred to as “power supply stop target device” as appropriate) (step S105).

  When the power supply stop target device is specified, the power management server 10 assigns the electric device ID of the electric device whose power supply is to be stopped to the store terminal 21 connected to the electric device whose power supply is to be stopped. A compulsory power supply stop instruction command for instructing to perform an instruction to forcibly stop power supply to the electric device indicated by the presented electric device ID is transmitted (step S106).

  When the store terminal 21 receives the forced power supply stop instruction command, the store terminal 21 outputs a power supply stop signal for instructing the power supply stop (power switch off) to each of the electrical equipments indicated by the presented electrical equipment IDs. Transmit (step S107).

  Upon receipt of the power supply stop signal, each electrical device transmits a power supply stop completion notification indicating that the power supply is stopped by executing a power supply stop process to the store terminal 21, and then Stop processing (processing to turn off the power switch) is executed.

  When the store terminal 21 receives the power supply stop completion notification from all the electric devices (step S108), the power supply stop completion for reporting that the power supply to all the corresponding electric devices has been stopped is completed. The report is transmitted to the power management server 10 (step S109). Note that if a power supply stop completion notification is not transmitted from some of the electric devices even after waiting for a certain period of time, the store terminal 21 indicates the electric devices that have completed the stop of the power supply. A power supply stop completion report including the ID may be transmitted.

  When the power management server 10 receives the power supply stop completion report, the power management server 10 creates a power supply stop completion status display screen for notifying the electric device that has been stopped to supply power, and displays the generated power supply stop completion status display. The screen is displayed on the display device provided in itself (step S110), and the process proceeds to step S101. The power supply stop completion status displayed on the power supply stop completion status display screen is updated each time a power supply stop completion report is received, for example, when receiving a power supply stop completion report from a plurality of store terminals.

  FIG. 5 is an explanatory diagram illustrating an example of a power supply stop completion status display screen. As shown in FIG. 5, the power supply stop completion status display screen includes a display area 101 for displaying the power supply stop completion status, a display area 101 for displaying the total amount of power reduced by the power supply stop, and the power supply stop. An end button 103 that is pressed when closing the completion status display screen is provided.

  The administrator X grasps the power supply stop completion status by viewing the display area 101 of the power supply stop completion status display screen, and grasps the total amount of power reduced by viewing the display area 101.

  As described above, the power management server 10 instructs the electrical terminal to forcibly stop the power supply to the store terminal 21, and supplies power to the electrical device according to the instruction of the store terminal 21. An emergency stop process is executed.

  FIG. 6 is a flowchart showing another example of the power management process in the power management system 100 of this example. Here, in response to the operation of the administrator X managing the power management server 10, the power management server 10 issues an instruction to start power supply to the store terminal 21 (that is, an instruction to cancel the stop of power supply). An instruction is given to the electric device (that is, here, only information related to the store A is registered in the power management master), and power supply to the electric device is started by an instruction from the store terminal 21. A case will be described as an example. It should be noted that explanations may be omitted except for processing particularly related to the present invention.

  In this example, it is assumed that the power management process is always executed while the power management server 10 is in operation.

  In the power management process, first, the power management server 10 determines whether or not the power company provision information has been acquired (step S201). Here, if it determines with not acquiring electric power company provision information (N of step S201), the power management server 10 will transfer to the process of step S204 mentioned later.

  On the other hand, for example, if it is determined that the power company provision information has been acquired from a predetermined server device managed by the power company (Y in step S201), the power management server 10 calculates the expected power usage rate using a predetermined calculation formula. (Step S202) (see FIG. 2).

  When the predicted power usage rate is calculated, the power management server 10 refers to the power management master and the information provided by the power company, and the calculated predicted power usage rate is lower than the power saving execution power usage rate indicated by the power saving level. (Hereinafter referred to as “power saving cancellation ratio”) is specified (hereinafter referred to as “power saving cancellation time zone”) (step S203).

  When the power saving release time zone is specified, the power management server 10 specifies the current time by a known method, and the current time is a predetermined time before the specified power saving release time zone (for example, 5 minutes before). It is determined whether or not (step S204). If it is determined that the specified power saving cancellation time zone has not been reached (N in step S204), the power management server 10 proceeds to the process in step S201.

  On the other hand, if it is determined that the specified power saving release time zone has been reached (Y in step S204), the power management server 10 refers to the power management master and is stopping (or stopping) the supply of electricity as a power supply suspension target. The electrical device is specified (step S205). In addition, as a method for specifying an electrical device, for example, the power management server 10 may refer to a history of power management processing, or may acquire information related to the operating status of the electrical device from the store terminal 21. .

  When the electric device whose power supply is stopped is specified, the power management server 10 presents the electric device ID of the electric device whose power supply is stopped to the store terminal 21 connected to the electric device whose power supply is stopped. Then, a forced power supply stop release instruction command for instructing to supply power to the electric device indicated by the presented electric device ID (instruction to release the stop of electric supply) is transmitted (step S206).

  When the store terminal 21 receives the forced power supply stop cancellation instruction command, the store terminal 21 outputs a power supply stop cancellation signal for instructing power supply (power switch on) to each electric device indicated by the presented electric device ID. Transmit (step S207).

  When each electric device receives the power supply stop release signal, it transmits a power supply stop release completion notification indicating that the power supply stop state has been released by executing a power supply stop release process to the store terminal 21. Then, the power supply stop cancellation processing (processing to turn on the power switch) is executed.

  When the store terminal 21 receives the power supply stop cancellation completion notification from all of the electrical devices (step S208), the store terminal 21 has completed stopping and releasing the power supply of all the corresponding electrical devices (that is, starting the electrical supply). A power supply stop cancellation completion report for reporting the fact is transmitted to the power management server 10 (step S209). In addition, even if it waits for a fixed period, when the notification of completion of power supply stop cancellation is not transmitted from some of the electrical devices, the shop terminal 21 indicates each of the electrical devices for which the suspension of power supply has been completed. A power supply stop cancellation completion report including the electric device ID may be transmitted.

  When the power management server 10 receives the power supply stop cancellation completion report, the power management server 10 creates a power supply stop cancellation completion status display screen for notifying the electrical device that has been completed to cancel the power supply stop, and the generated power supply stop The cancellation completion status display screen is displayed on the display device provided in itself (step S210), and the process proceeds to step S201. The power supply stop cancellation completion status displayed on the power supply stop cancellation completion status display screen is updated each time a power supply stop cancellation completion report is received, for example, when receiving a power supply stop cancellation completion report from a plurality of store terminals. The

  The administrator X grasps the power supply stop cancellation completion status by browsing the power supply stop cancellation completion status display screen, and grasps the increased total power.

  As described above, the power management server 10 instructs the store terminal 21 to forcibly stop the power supply to the electrical device, and the power to the electrical device is instructed by the store terminal 21. A process of canceling the supply stop (that is, restarting the power supply) is executed.

  In the above example, the power management server 10 mainly instructs the electric device to instruct the one store terminal 21 to forcibly stop (or start. See, FIGS. 4 and 6) the electric power supply. Although the case has been described, the power management server 10 may instruct an electrical device to instruct the plurality of store terminals to forcibly stop (or start) the power supply. When the power management master as shown in FIG. 2 is registered, each terminal (the store terminal 21 and the delivery center terminal 22) managed by the store A and the delivery center A is forcibly powered. Processing for instructing the electric device to instruct to stop (or start) the supply is executed. The stop and start of power supply need not be compulsory. For example, the manager of the store terminal 21 may be prompted to stop or start power supply by voice output or the like.

  In the above example, the power management server 10 is configured to issue an instruction to stop (or start) power supply to each electrical device via the store terminal 21, but the power management server 10 directly supplies power to each electrical device. It may be configured to give an instruction to stop (or start) the supply.

  In the above example, the process of forcibly stopping (or starting) the power supply to the electrical equipment installed in the retail store is described. However, the electrical equipment is installed not in the retail store, It may be an equipment using electric equipment that is equipment using a plurality of electric equipment such as a distribution center.

  As described above, in the above-described embodiment, the power management server 10 that manages the power supply of the electrical equipment that operates by the supplied power has the power saving level at a plurality of stages and the power saving level at each stage. A power management master DB 11 that stores a power management master in which electrical device information indicating each associated electrical device is set, and a power company provision information that stores power company provision information acquired from a server device managed by the power company DB 12 is provided, and an expected power usage rate for which a future power usage rate is predicted is derived based on the information provided by the power company, and the predicted power usage rate derived by referring to the power management master indicates each of the plurality of power saving levels. Specify a time zone that exceeds the power usage rate of each power-saving implementation, and the expected power usage rate exceeds the time zone specified by referring to the power management master When an electrical device associated with a power saving level equal to or lower than the power saving level indicating the power saving implementation power usage rate is specified, the specified time is reached (for example, 5 minutes before) before reaching the specified time zone. The power supply stop command (forced power supply stop instruction command: see step S106) for instructing the stop of power supply to the specific electrical device indicating the performed electrical device is transmitted via the communication network 30. On the other hand, the amount of power used can be controlled within a safe range.

  That is, the power management server 10 refers to a power management master in which a plurality of predetermined power saving levels and electric device information indicating electric devices respectively associated with the power saving levels of each step are set. Based on the information provided by the power company, the expected power usage rate is derived, the time period in which the expected power usage rate exceeds the power saving implementation power usage rate is specified, and the power saving implementation power that exceeds the expected power usage rate in the specified time zone When an electrical device associated with a power saving level equal to or lower than the power saving level indicating the usage rate is identified and the predetermined time before reaching the identified time zone is reached, power supply to the specific electrical device indicating the identified electrical device is performed. Since the power supply stop command for instructing the stop is transmitted via the communication network 30, the actual power usage rate does not exceed the power saving implementation power usage rate as much as possible. Gosuru it will be able to, at the it it is possible to control the amount of electric power used in the safe range to the supply power amount. The higher the ratio of the total power consumption of each electrical device that is the control target with respect to the total power supply by the electric power company, the more remarkable the above effect. Moreover, since it is set as the above structures, it becomes possible to continuously suppress the power usage rate below a certain range, and it is possible to propose a reduction in the total amount of power supplied to the power company. . As a result, it can also be expected to reduce the power charge.

  In the above-described embodiment, the power company provision information includes the power usage amount on the previous day and the power usage on the previous day, and the power management server 10 performs the power usage on the previous day and the power on the previous day. Since the expected power usage rate is derived based on the usage amount, it is possible to derive an expected power usage rate close to the actual power usage rate based on the information provided by the power company.

  In the above-described embodiment, the power company provision information includes the expected power usage rate, and the power management server 10 derives the expected power usage rate included in the power company provision information as the expected power usage rate.
